ALMON-A. REED, OF 'ALCES'IlER,\-S OU'.DH DAKO 'IA.

, seam n-warm- To all whom it may concern:

Be it known that I, A L ron A. :Bnnn, a citizen of the United 'S tates, I residing at Alcester, in the county of Union and State of South Dakota, have invented certain new anldhs h Im rovemen i p f eh, of which the following is A a specification.

This invention relates to improvements in wheels of the classlofivspring Wheels, and'has for one of its objects to provide an'attachment including an improved arrangement of a spring supportedti're and, a of.

Y yieldable. cushiondevices which become operative when the "loadi upon the axle is increased beyond the normal.

NVith these and other objects in view, the' inventionconsists in certain novel features of construction, as hereinafter shown and scribed and then specifically pointed out in h claims and in th drawin s llu ra v of the preferred embodimentjof the inven- 9 1+ i Figure l is a Side Glevationparjtly in sectionfof a I portion of a wheel'with the im iir r hieh anp e Fist-. agsec Fig.1;

3hrrohhdiha,thei i hdePaQ@ a from is a relatively thick tire member,- 14,

the width of the tire corresponding "to the telly 13, as shown in Fig. 2. Bearing upon the side faces of the telly 13 are annular supporting plates 15-16, the plates being rigidly coupled to the telly by. clamp bolts.

17 The plates 15 and 16 are thus free to move over the side faces of the tire 14.

Disposed between each pair of the spokes 12 is an endless yoke frame 18, with its sides converging toward the axle and in parallel relation to the spokes. Eachyoko member is coupled to the hub by a clip'19, and bolt 20;

the latter preferably being oneof the usual clamp bolts whereby the flanges I of; the hub areunited, Slidably' disposed through the wider end of 'each of the yoke-members is a pull rod21 havinga bearing plate 22heldin place by a nut, and a spring-:23 surroundingeach rod between theheadandi the wider outer end;

of the yoke; 18. "its" outer end I eaclr'of the rods 21 is providedzwith head 24,. and surrounding eachrod beneath the" head a transverse yoke member 26 having inwardly directed ter iiinalfs'or: hooks EX- tending transversely through the tire 14:1 in

radial alinement each of the rods is another h ving-f inwardly directed portions 30 31' terminating in hooks'32 33:

Flexible members, preferably sections of chain- 3 1F535, are coupled their terminal links respectively with'the hooks '27-28' and 32%33. By this" means itwilh be obvious that'the tire 14"is yieldably supported rela ively h ho yfef' thefwheehfihdi y downward pressure upon the axle 10 will be borne by the yielda lemembers by which the tireis supportedxr The springs 23 will be of sufficient t en a tain the t r n rma y; in hqli eh r c lat ll t thef ly 1 b 1 th ent. i abnorm pressu be ng ap to theQagile bylan inerease" in theiload the y k 8,, .hi; f jh tiinebfeina a e ahhv th en ra l heo h h will be mov downwardlyf against the resistance ,of the springs 2. and Prevent iar 'ptfeo c se hns hsiligii ohlmun ea e t he bedylo th ye hicle, this ,means an efiectual, 311d efficient spring wheel" is produced which will pra t c lly a sorb the anal-see an ii me t i lmq ing Drier. the. oada Slidabl di' posedthrough the felly 13"are tanda ds [36, 911 27 1 ersta da dsb in disposed in radial "alin'eme'nt with each of the yokes l8 and the rods 21, as 'shown in Fig. 1. At its inner end each of the standards 36 is provided with a stop head 37 bearing against the inner face of the felly and limiting the outward movement, and attached to or formed integral with each standard 36 at its outer end is a bearing 'member 38 preferably in segmental form, Slidablydisposed in the telly 13 and spaced from each of the standards 36 are radial bearing against the inner face of the felly:

and with rounded heads 41 at their outer ends bearing against the inner face of the segmental members 38. A spring 42 surheads 41 and the felly 13 and thus operates to yieldably support the plates 38 in their outward position with theheads 37 of the standards 36 maintained against the inner face of the felly. An anti-friction ball 413 is supported upon theouter face of each of the members 38 and adapted to be engaged by the inner face of the movable tirel l when the relative positions of the members 13 1 1 arechanged under the stress ofthe load. The standards 36 together with the segmental members 38 coact with the spring absorbing elements 42 which become effective when an abnormal; load is applied to the axle, and thus rel eve the springs 23 and yokes 18 from undue, strain. The cushion-v ing devices and the spring supported yokes thus coact to increase the efficiency and utility of the wheel and correspondingly. increase its shock resisting properties and relieve thel'body of the vehicle from concussions and jarring movements. 5

Keepers 4A are attached to the plates 15-46, preferably by the samebolts 17 by which; the plates aresecured to the felly, and extend over the flexible members 34 -85,

to preventundue lateral movement thereof,

The tire 1% is provided with an outwardly opening annular channel, indicated at 45, and lying in this channel is an encircling tie rod46, which materially strengthens and supports the tire. I r I v i n In Fig; 5 aimodification in the construetion is shown consisting in substituting for the transverse yoke 26 and its hooked ter.

minals 27+28 a radially disposed bolt 47 passing through the tire 14: and havinga head 48 at the outer end embedded therein and with an eye49 at the inner end. A single chain or 'otlienfiexible member 50 connects the eye l9 ,with bolt '21 and passes through an o aperture indicated at 51, through the felly'l3. r q f .t.

In the modified structure, two of the standards 36 and their anti-friction balls as will berequired; one on each side of the Gopies'of this nstant may be obtainedror chain 50, as shown in Fig. 5. The ape1- tures. for the standards 36 will be necessarily enlarged to a sufficient extent to permit the requisite lateral play to the bolts I I when the plate 38 is forced inwardly. rounds each of therod's' -39 between the The structure disclosed in Fig. 5 does not constitute a departure from the principle of the invention or sacrifice any of its advantages,

I Having thus described the invention, what is claimed as new is:

i 1. The combinationwith a wheel including a hub, and felly, of a tire of greater diameterthan the felly and spaced therefrom, a plurality of yoke devices connected to the hub, a yieldable member connected to each yoke device, a flexible connecting means between each yieldable member and the tire, a plurality of bearing members 'dis posed between the felly and tire, means for limiting the outward movement of the bearing members, and spring controlled stop bolts carried by the felly and engaging the bearing members and yieldably holding them from inward movement.

2. The combination with a wheel including a hub and felly, of a tire of greater diameter than the felly and spaced therefrom, means for yieldably coupling said tire to thebody of the Wheel, a plurality of rods movable through-the felly and each having a, laterally directed member spaced nor-;

body of the wheel, a plurality of rods movable through. the felly andeachhaving a laterally directed member spaced ,normally from the tire, other rods movable through said 1 felly, and springs operating to maintain said lastflmentioned rods in yieldable engagement with the laterally directed members and adapted to resist abnormal eccen trio movement of thetire,

In testimony whereof I afiix my signature.
